Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
t
=1
R = 23
To find this, first combine distribute the numbers, then combine like terms:
4x - 12 - r + 2x = 15x - 35 - 9x
6x - 12 - r = 6 x - 35
Here, the 6x's cancel out so you're left with constants.
-12 - r = - 35
-r = -23
And since -r still is negative, you'll have to divide by - to cancel it out on both sides, leaving you with positive 23 as r.
Hope this helps!
It will take it 2 hours because if it is swimming 9 miles per hour in two hours it will have swam 18 miles because 9x2=18
Answer:
LEAST DIFFICULT: B
MOST DIFFICULT: I
Step-by-step explanation:
LEAST DIFFICULT:
The easiest systems of equations to solve are ones in which x or y is equal to just a number , because in this case, you can just sub in that number in the other equations. Though not the only one, B is an example of this.
MOST DIFFICULT:
More difficult systems of equations to solve are the ones with different amounts of x and y as it requires more computation. Set I is an example of this
